Herbs, perennial, aquatic, rhizomatous; roots adventitious; air chambers conspicuous in vegetative portions of plant. Rhizomes branched or unbranched, erect or repent, tuberous-thickened, sometimes bearing stolons. Leaves arising directly from rhizome, alternate, floating, submersed, or emersed; stipules present or absent; petioles long. Leaf blade lanceolate to ovate or orbiculate, with basal sinus [peltate], margins entire to spinose-dentate. Inflorescences axillary or extra-axillary, flowers solitary. Flowers bisexual, protogynous [homogamous in some species of Nymphaea], diurnal or nocturnal, borne at or above water surface, occasionally submersed; peduncle long; involucre absent; perianth often persistent in fruit, hypogynous to perigynous [epigynous]; sepals usually (4-)5-12, distinct; petals numerous [rarely absent], often transitional to stamens; stamens numerous; filaments broad to slender; anthers dehiscing by longitudinal slits, with or without connective appendage; pistil 1, 3-35-carpellate and -locular; placentation laminar; ovules numerous per locule; stigma sessile, radiate on stigmatic disk. Fruits berrylike, indehiscent or irregularly dehiscent. Seeds several-numerous; aril present or absent; endosperm sparse; perisperm abundant; embryo minute; cotyledons 2, fleshy.
Distribution
Nearly worldwide.
Discussion
Genera 6 (including Barclaya), species ca. 50 (2 genera, 17 species in the flora).
Nymphaeaceae are insect-pollinated, often by beetles.
Formerly Nymphaeaceae often have been treated to include Cabombaceae and Nelumbonaceae, but these are now generally segregated.
